We present a brief description of the main results obtained on the following topics: (1) Sulfur-bearing molecules in O-rich envelopes: SO2(104 and 160 GHz), H2S (169 and 217 GHz) in 15 stars, SO (86 GHz) in 7 stars (all new detections except H2S in 0H231.8+4.2). Excitation temperatures and line profiles could suggest in some stars a main contribution from external layers for SO2 and internal layers for H2S.
